　次に、図２を参照して、本実施例の情報提供システム１２における動作について説明する。図２は、本実施例の情報提供システム１２において車載情報処理装置１０及び携帯端末１４が実行するルーチンの一例のフローチャートを示す。 Next, the operation of the information providing system 12 according to this embodiment will be described with reference to FIG. FIG. 2 shows a flowchart of an example of a routine executed by the in-vehicle information processing apparatus 10 and the portable terminal 14 in the information providing system 12 of the present embodiment.
　本実施例の情報提供システム１２において、車載機としての車載情報処理装置１０は、車両における電源状態がオフ状態からアクセサリ（ＡＣＣ）オン状態に移行した後、自車両の車室内に存在する携帯端末１４と近距離無線通信接続（ブルートゥース接続）することが可能である。 In the information providing system 12 of the present embodiment, the in-vehicle information processing apparatus 10 as the in-vehicle device is a portable terminal that exists in the vehicle interior of the host vehicle after the power state in the vehicle has shifted from the off state to the accessory (ACC) on state. 14 can be connected by short-range wireless communication (Bluetooth connection).
　車載情報処理装置１０の制御回路４２は、車両における電源状態がアクセサリ（ＡＣＣ）オン状態に移行すると、自動的に或いは所定操作が行われることにより、ＢＴ５４から携帯端末１４とのブルートゥース接続を要求することを示す信号を送信させる（ブルートゥース接続要求）。携帯端末１４は、車載情報処理装置１０からのブルートゥース接続要求を示す信号をＢＴ２８で受信することが可能である。携帯端末１４の制御回路１６は、車載情報処理装置１０からのブルートゥース接続要求を示す信号を受信すると、そのブルートゥース接続要求に対して応答を許可するときは、そのブルートゥース接続の応答ＯＫを示す信号をＢＴ２８から送信させる。 The control circuit 42 of the in-vehicle information processing apparatus 10 requests the Bluetooth connection from the BT 54 to the portable terminal 14 automatically or when a predetermined operation is performed when the power state in the vehicle shifts to the accessory (ACC) on state. A signal indicating that this is transmitted (Bluetooth connection request). The mobile terminal 14 can receive a signal indicating a Bluetooth connection request from the in-vehicle information processing apparatus 10 by the BT 28. When the control circuit 16 of the portable terminal 14 receives the signal indicating the Bluetooth connection request from the in-vehicle information processing apparatus 10 and permits the response to the Bluetooth connection request, the control circuit 16 transmits a signal indicating the response OK of the Bluetooth connection. It is transmitted from BT28.
　車載情報処理装置１０がブルートゥース接続要求を示す信号を送信した後に携帯端末１４からのブルートゥース接続応答ＯＫを示す信号を受信すると、以後、車載情報処理装置１０と携帯端末１４との間のブルートゥース接続が完了し、車載情報処理装置１０と携帯端末１４とは互いにブルートゥース接続される。 When the in-vehicle information processing apparatus 10 receives the signal indicating the Bluetooth connection response OK from the portable terminal 14 after transmitting the signal indicating the Bluetooth connection request, the Bluetooth connection between the in-vehicle information processing apparatus 10 and the portable terminal 14 is subsequently performed. The in-vehicle information processing apparatus 10 and the mobile terminal 14 are connected to each other via Bluetooth.
　かかるブルートゥース接続が実現されると、車載情報処理装置１０の制御回路４２は、自動的に或いは所定操作が行われることにより、ＢＴ５４から携帯端末１４にメモリ２２内に格納されている電話帳や発着信履歴に関する情報（以下、ＰＢＡＰ（Phone Book Access Profile）情報と称す）を転送するように要求することを示す信号を送信させる（ＰＢＡＰ要求）。携帯端末１４の制御回路１６は、車載情報処理装置１０からのＰＢＡＰ要求を示す信号を受信すると、メモリ２２に格納している電話帳や発着信履歴のＰＢＡＰ情報をＢＴ５４から送信させる。 When such Bluetooth connection is realized, the control circuit 42 of the in-vehicle information processing apparatus 10 automatically or by performing a predetermined operation, the phone book stored in the memory 22 from the BT 54 to the portable terminal 14 A signal indicating that a request to transfer information related to the incoming call history (hereinafter referred to as PBAP (Phone Book Access Profile) information) is transmitted (PBAP request). When receiving the signal indicating the PBAP request from the in-vehicle information processing apparatus 10, the control circuit 16 of the mobile terminal 14 causes the BT 54 to transmit the phone book stored in the memory 22 and the PBAP information of the outgoing / incoming call history.
　携帯端末１４のメモリ２２に格納されている発着信履歴の情報は、通話の発着信が行われた国や地域における時刻を示すローカル時刻によるものである。携帯端末１４は、表示部１６に通話の発着信履歴をローカル時刻で表示することが可能である。また、携帯端末１４が車載情報処理装置１０からの要求に従って送信するＰＢＡＰ情報に含まれる発着信履歴の情報は、通話の発着信が行われた国や地域における時刻を示すローカル時刻自体によるものであってもよいし、また、通話の発着信が行われた国や地域におけるローカル時刻を協定世界時ＵＴＣ（或いは、グリニッジ標準時ＧＭＴ）に変換したものであってもよく、その通話履歴を示す時刻がその携帯端末１４に応じてローカル時刻及び協定世界時ＵＴＣの何れか一方に定まるものであればよい。 The information of the outgoing / incoming call history stored in the memory 22 of the mobile terminal 14 is based on the local time indicating the time in the country or region where the incoming / outgoing call is made. The mobile terminal 14 can display the call origination / reception history on the display unit 16 in local time. In addition, the outgoing / incoming history information included in the PBAP information transmitted by the mobile terminal 14 in accordance with a request from the in-vehicle information processing apparatus 10 is based on the local time itself indicating the time in the country / region where the outgoing / incoming call is made. Alternatively, the local time in the country or region where the call is made or received may be converted to Coordinated Universal Time UTC (or Greenwich Mean Time GMT), and the time indicating the call history May be determined according to the mobile terminal 14 as either local time or UTC.
　車載情報処理装置１０がＰＢＡＰ要求を示す信号を送信した後に携帯端末１４からのＰＢＡＰ情報を受信すると、その制御回路４２は、そのＰＢＡＰ情報に基づいて携帯端末１４での通話の発着信履歴情報を取得する。ここで、車載情報処理装置１０がすべての携帯端末１４から取得する発着信履歴情報が常にローカル時刻によるもの又は常に協定世界時ＵＴＣによるものに固定されているものとして、制御回路４２が、取得した発着信履歴情報に含まれる時刻情報を、ローカル時刻情報としてそのまま補正することなく利用し（例えば、表示部５２に表示し）、或いは、協定世界時ＵＴＣによるものとして一律に補正する（例えば、日本標準時として＋９時間を足した時刻情報を表示部５２に表示する）ものとすると、車載情報処理装置１０で提供する携帯端末１４での発着信履歴情報が、その履歴が示す地域や履歴場所における正確な現地時刻情報を示さないことが起こり得る。 When the in-vehicle information processing apparatus 10 receives the PBAP information from the portable terminal 14 after transmitting the signal indicating the PBAP request, the control circuit 42 displays the call history information of the call at the portable terminal 14 based on the PBAP information. get. Here, the control circuit 42 acquires that the call history information acquired by the in-vehicle information processing device 10 from all the mobile terminals 14 is always fixed to the local time or always based on the Coordinated Universal Time UTC. The time information included in the outgoing / incoming call history information is used as it is without being corrected as local time information (for example, displayed on the display unit 52), or is corrected uniformly according to the Coordinated Universal Time UTC (for example, Japan If the time information obtained by adding +9 hours as standard time is displayed on the display unit 52), the call history information on the mobile terminal 14 provided by the in-vehicle information processing apparatus 10 is accurate in the area or history location indicated by the history.

　例えば、携帯端末１４が車載情報処理装置１０へ向けて送信するＰＢＡＰ情報に含まれる発着信履歴の情報が、その携帯端末１４での通話の発着信が行われた日本国における時刻を示すローカル時刻によるものであるにもかかわらず、車載情報処理装置１０が携帯端末１４から取得した発着信履歴情報が常に協定世界時ＵＴＣによるものであると仮定して、制御回路４２が取得した発着信履歴情報に含まれる時刻情報を一律に＋９時間を足した時刻情報に補正するものとすると、車載情報処理装置１０が提供する携帯端末１４での発着信履歴情報としてのローカル時刻情報が、携帯端末１４での実際の発着信履歴情報に含まれるローカル時刻情報に対して＋９時間だけ進むこととなり、その結果として、時刻のズレが生じてしまう（尚、図２における上段側の携帯端末１４の表示部と車載情報処理装置１０の表示部との表示内容を比較して参照）。 For example, the local time in which the information of the outgoing / incoming history included in the PBAP information transmitted from the mobile terminal 14 to the in-vehicle information processing apparatus 10 indicates the time in Japan when the outgoing / incoming call is performed on the mobile terminal 14. Despite this, the call history information acquired by the control circuit 42 on the assumption that the call history information acquired from the mobile terminal 14 by the in-vehicle information processing apparatus 10 is always based on the Coordinated Universal Time UTC. If the time information included in the mobile terminal 14 is uniformly corrected to the time information obtained by adding +9 hours, the local time information as the outgoing / incoming history information at the mobile terminal 14 provided by the in-vehicle information processing apparatus 10 is The local time information included in the actual outgoing / incoming call history information is advanced by +9 hours, resulting in a time shift (see FIG. Reference by comparing the display contents of the display portion of the upper side of the portable terminal 14 and the display unit of the vehicle information processing apparatus 10 in).
　そこで、本実施例の車載情報処理装置１０を含む情報提供システム１２は、携帯端末１４での履歴情報を車載情報処理装置１０で提供するうえでの時刻情報の正確性を向上させることとしている。 Therefore, the information providing system 12 including the in-vehicle information processing apparatus 10 according to the present embodiment is to improve the accuracy of the time information when the in-vehicle information processing apparatus 10 provides the history information in the portable terminal 14.
　すなわち、本実施例の情報提供システム１２において、車載情報処理装置１０と携帯端末１４とがブルートゥース接続されている状況で、車載情報処理装置１０を用いてその携帯端末１４から通話の発信がなされ、或いは、その携帯端末１４に通話の着信がなされると、車両乗員は、車載情報処理装置１０の有するマイクロフォン５８及びスピーカ６０を通じて、ブルートゥース接続がなされたその携帯端末１４を手に取ることなく他人と通話することが可能である。かかる通話が終了すると、携帯端末１４のメモリ２２には、その通話の発着信履歴情報がその通話が行われた国や地域におけるローカル時刻を含んで格納されることとなる。 That is, in the information providing system 12 of the present embodiment, in a situation where the in-vehicle information processing apparatus 10 and the mobile terminal 14 are connected via Bluetooth, a call is transmitted from the mobile terminal 14 using the in-vehicle information processing apparatus 10. Alternatively, when an incoming call is made to the mobile terminal 14, the vehicle occupant can communicate with another person through the microphone 58 and the speaker 60 of the in-vehicle information processing apparatus 10 without picking up the mobile terminal 14 that has been Bluetooth-connected. It is possible to make a call. When such a call ends, the memory 22 of the mobile terminal 14 stores the call origination / incoming history information including the local time in the country or region where the call was made.
　車載情報処理装置１０の制御回路４２は、車載情報処理装置１０と携帯端末１４とがブルートゥース接続されている状況で通話が行われ、その通話が終了すると、その通話終了直後、ＢＴ５４から携帯端末１４にメモリ２２内に格納されているＰＢＡＰ情報を転送するように要求することを示す信号を送信させる（ＰＢＡＰ要求）。携帯端末１４の制御回路１６は、車載情報処理装置１０からのＰＢＡＰ要求を示す信号を受信すると、メモリ２２に格納している電話帳や発着信履歴のＰＢＡＰ情報をＢＴ２８から送信させる。 The control circuit 42 of the in-vehicle information processing apparatus 10 performs a call in a situation where the in-vehicle information processing apparatus 10 and the mobile terminal 14 are connected via Bluetooth, and when the call ends, immediately after the end of the call, the control circuit 42 starts from the BT 54 to the mobile terminal 14. Transmits a signal indicating a request to transfer the PBAP information stored in the memory 22 (PBAP request). When receiving the signal indicating the PBAP request from the in-vehicle information processing apparatus 10, the control circuit 16 of the mobile terminal 14 causes the BT 28 to transmit the phone book stored in the memory 22 and the PBAP information of the outgoing / incoming call history.
　携帯端末１４のメモリ２２に格納されている発着信履歴情報は、通話の発着信が行われた国や地域における時刻を示すローカル時刻によるものであるが、上記した通話終了後の発着信履歴情報には、直前に車載情報処理装置１０とブルートゥース接続されている状況で行われた通話に係るローカル時刻が含まれている筈である。このため、車載情報処理装置１０と携帯端末１４とがブルートゥース接続されている状況での通話終了後に携帯端末１４から車載情報処理装置１０に送られるＰＢＡＰ情報は、最新の発着信履歴に基づくものとなる。 The outgoing / incoming call history information stored in the memory 22 of the portable terminal 14 is based on the local time indicating the time in the country or region where the incoming / outgoing call is made. Includes a local time relating to a call made immediately before in-vehicle information processing apparatus 10 and Bluetooth connection. For this reason, the PBAP information sent from the portable terminal 14 to the in-vehicle information processing apparatus 10 after the end of the call in a state where the in-vehicle information processing apparatus 10 and the portable terminal 14 are connected via Bluetooth is based on the latest outgoing / incoming history. Become.
　一方、携帯端末１４が車載情報処理装置１０に対して送信するＰＢＡＰ情報に含まれる発着信履歴の情報は、上記の如く、その携帯端末１４に応じてローカル時刻自体及び協定世界時ＵＴＣの何れか一方に定まっている。車載情報処理装置１０の制御回路４２は、その携帯端末１４が車載情報処理装置１０に対して送信して車載情報処理装置１０が携帯端末１４から受け取るＰＢＡＰ情報に含まれる発着信履歴の情報がローカル時刻自体及び協定世界時ＵＴＣの何れによるものであるか否かを判定すべく、以下の処理を実行する。 On the other hand, as described above, the outgoing / incoming call history information included in the PBAP information transmitted from the mobile terminal 14 to the in-vehicle information processing apparatus 10 is either the local time itself or the Coordinated Universal Time UTC according to the mobile terminal 14. It is fixed on one side. The control circuit 42 of the in-vehicle information processing apparatus 10 has local information on the outgoing / incoming history included in the PBAP information transmitted from the mobile terminal 14 to the in-vehicle information processing apparatus 10 and received by the in-vehicle information processing apparatus 10 from the mobile terminal 14. In order to determine whether the time itself or Coordinated Universal Time UTC is used, the following processing is executed.
　すなわち、制御回路４２は、車載情報処理装置１０と携帯端末１４とがブルートゥース接続されている状況で通話が行われたときに、時計機能６４を用いてすなわちＧＰＳ衛星５５からのＧＰＳ信号に含まれる協定世界時ＵＴＣを用いて、その通話時点の自車両位置におけるローカル時刻情報を算出する。また、制御回路４２は、車載情報処理装置１０と携帯端末１４とがブルートゥース接続されている状況での通話終了後に携帯端末１４から最新の発着信履歴に基づくＰＢＡＰ情報を取得する。そして、制御回路４２は、上記の如く算出した通話時点のローカル時刻と、上記の如く携帯端末１４から取得した最新の発着信履歴における時刻（特に、最終通話履歴の時刻）と、の比較を行う（ステップ１００）。 That is, the control circuit 42 is included in the GPS signal from the GPS satellite 55 using the clock function 64 when a call is made in a state where the in-vehicle information processing apparatus 10 and the mobile terminal 14 are connected via Bluetooth. Using the Coordinated Universal Time UTC, the local time information at the vehicle position at the time of the call is calculated. Further, the control circuit 42 acquires PBAP information based on the latest outgoing / incoming call history from the mobile terminal 14 after the call in the situation where the in-vehicle information processing apparatus 10 and the mobile terminal 14 are connected via Bluetooth. Then, the control circuit 42 compares the local time at the time of the call calculated as described above with the time (particularly, the time of the last call history) in the latest outgoing / incoming call history acquired from the mobile terminal 14 as described above. (Step 100).
　これらの比較される２つの時刻の間には、携帯端末１４が車載情報処理装置１０に対して送信するＰＢＡＰ情報に含まれる発着信履歴情報がローカル時刻によるものであるときは、差が生じないが、一方、携帯端末１４が車載情報処理装置１０に対して送信するＰＢＡＰ情報に含まれる発着信履歴情報が協定世界時ＵＴＣによるものであるときは、差が生じる。 There is no difference between the two compared times when the outgoing / incoming call history information included in the PBAP information transmitted from the mobile terminal 14 to the in-vehicle information processing apparatus 10 is based on the local time. On the other hand, when the outgoing / incoming history information included in the PBAP information transmitted from the mobile terminal 14 to the in-vehicle information processing apparatus 10 is based on Coordinated Universal Time UTC, a difference occurs.
　例えば、日本国内で車載情報処理装置１０と携帯端末１４とがブルートゥース接続されている状況で通話が行われたローカル時刻（日本標準時）が４月２１日２０時３０分である場合において、携帯端末１４が車載情報処理装置１０に対して送信するＰＢＡＰ情報に含まれる発着信履歴情報が日本国のローカル時刻によるものであるときは、車載情報処理装置１０が携帯端末から受け取る発着信履歴情報の時刻は、ローカル時刻である４月２１日２０時３０分である。一方、携帯端末１４が車載情報処理装置１０に対して送信するＰＢＡＰ情報に含まれる発着信履歴情報が協定世界時ＵＴＣによるものであるときは、車載情報処理装置１０が携帯端末から受け取る発着信履歴情報の時刻は、協定世界時ＵＴＣである４月２１日１１時３０分であり、ローカル時刻に対して－９時間となる。 For example, in the case where the local time (Japan Standard Time) when a call is made in a state where the in-vehicle information processing apparatus 10 and the mobile terminal 14 are connected via Bluetooth in Japan is 20:30 on April 21, the mobile terminal When the outgoing / incoming history information included in the PBAP information transmitted to the in-vehicle information processing apparatus 10 is based on the local time in Japan, the time of the incoming / outgoing history information received by the in-vehicle information processing apparatus 10 from the portable terminal Is the local time of April 21, 20:30. On the other hand, when the outgoing / incoming history information included in the PBAP information transmitted from the mobile terminal 14 to the in-vehicle information processing apparatus 10 is based on Coordinated Universal Time UTC, the outgoing / incoming history received by the in-vehicle information processing apparatus 10 from the mobile terminal The time of the information is 11:30 on April 21, which is UTC, which is -9 hours relative to the local time.
　車載情報処理装置１０の制御回路４２は、上記の時刻比較の結果、両時刻の間に所定以上の差が無いときは、携帯端末１４が車載情報処理装置１０に対して送信して車載情報処理装置１０が携帯端末１４から受け取るＰＢＡＰ情報に含まれる発着信履歴情報がローカル時刻によるものであると判定する。尚、上記の「所定以上の差」とは、両時刻が略同じであると想定できる範囲を超えることの意味であって、例えば、１分や５分などの時間差に設定されている。 The control circuit 42 of the in-vehicle information processing apparatus 10 transmits the in-vehicle information processing by the mobile terminal 14 to the in-vehicle information processing apparatus 10 when there is no difference between the two times as a result of the time comparison. It is determined that the outgoing / incoming history information included in the PBAP information received by the device 10 from the mobile terminal 14 is based on the local time. The “difference greater than or equal to the above” means that the time exceeds a range where both times can be assumed to be substantially the same, and is set to a time difference such as 1 minute or 5 minutes, for example.
　かかる判定がなされると、以後、制御回路４２は、この携帯端末１４に対しては、その携帯端末１４から受け取るＰＢＡＰ情報に含まれる発着信履歴情報に含まれる時刻情報をそのまま補正することなく利用し、例えばその携帯端末１４からの発着信履歴情報に含まれる時刻情報を表示部５２に表示させる。この場合、車載情報処理装置１０の表示部５２には、当該携帯端末１４での通話の発着信履歴情報がローカル時刻で表示されることとなる。 When this determination is made, the control circuit 42 uses the mobile terminal 14 without correcting the time information included in the outgoing / incoming history information included in the PBAP information received from the mobile terminal 14 thereafter. For example, the time information included in the outgoing / incoming call history information from the mobile terminal 14 is displayed on the display unit 52. In this case, the outgoing / incoming call history information of the call on the mobile terminal 14 is displayed in the local time on the display unit 52 of the in-vehicle information processing apparatus 10.
　一方、制御回路４２は、上記の時刻比較の結果、両時刻の間に所定以上の差があるときは、携帯端末１４が車載情報処理装置１０に対して送信して車載情報処理装置１０が携帯端末１４から受け取るＰＢＡＰ情報に含まれる発着信履歴情報が協定世界時ＵＴＣによるものであると判定する。 On the other hand, when there is a difference of a predetermined value or more between the two times as a result of the above time comparison, the control circuit 42 transmits the mobile terminal 14 to the in-vehicle information processing apparatus 10 and the in-vehicle information processing apparatus 10 is It is determined that the outgoing / incoming history information included in the PBAP information received from the terminal 14 is based on Coordinated Universal Time UTC.
　かかる判定がなされると、以後、制御回路４２は、この携帯端末１４に対しては、その携帯端末１４から受け取るＰＢＡＰ情報に含まれる発着信履歴情報に含まれる時刻情報を、ローカル時刻と協定世界時ＵＴＣとの時差分だけ補正して利用し、例えば、日本国では＋９時間を足した時刻情報を表示部５２に表示させる（ステップ１１０）。この場合、車載情報処理装置１０の表示部５２には、当該携帯端末１４での通話の発着信履歴情報がローカル時刻で表示されることとなる。 When this determination is made, thereafter, the control circuit 42 gives the time information included in the outgoing / incoming call history information included in the PBAP information received from the mobile terminal 14 to the local time and the agreed world. For example, in Japan, the time information obtained by adding +9 hours is displayed on the display unit 52 (step 110). In this case, the outgoing / incoming call history information of the call on the mobile terminal 14 is displayed in the local time on the display unit 52 of the in-vehicle information processing apparatus 10.
　このように、本実施例の情報提供システム１２においては、車載情報処理装置１０と携帯端末１４とがブルートゥース接続されている状況で通話が行われた場合に、携帯端末１４が車載情報処理装置１０に対して送信して車載情報処理装置１０が携帯端末１４から取得した最新の発着信履歴情報における時刻を、その通話時点で車載情報処理装置１０がＧＰＳ信号に含まれる協定世界時ＵＴＣに基づく位置検出時に算出したローカル時刻と比較することにより、その携帯端末１４が車載情報処理装置１０に対して送信して車載情報処理装置１０が携帯端末１４から取得した最新の発着信履歴情報における時刻が、ローカル時刻であるか協定世界時ＵＴＣであるかを判定することができる。 As described above, in the information providing system 12 according to the present embodiment, when a call is performed in a state where the in-vehicle information processing apparatus 10 and the mobile terminal 14 are connected via Bluetooth, the mobile terminal 14 is connected to the in-vehicle information processing apparatus 10. The position in the latest outgoing / incoming call history information acquired from the mobile terminal 14 by the in-vehicle information processing apparatus 10 and the position based on the Coordinated Universal Time UTC included in the GPS signal at the time of the call By comparing with the local time calculated at the time of detection, the time in the latest outgoing / incoming history information that the mobile terminal 14 transmits to the in-vehicle information processing apparatus 10 and acquired by the in-vehicle information processing apparatus 10 from the mobile terminal 14 is It can be determined whether it is local time or Coordinated Universal Time UTC.
　そして、その携帯端末１４からの最新の発着信履歴情報における時刻がローカル時刻であるときはその時刻をそのまま補正することなくローカル時刻として利用し、一方、その携帯端末１４からの最新の発着信履歴情報における時刻が協定世界時ＵＴＣであるときはその時刻をローカル時刻に補正して利用することができる。 And when the time in the latest outgoing / incoming call history information from the mobile terminal 14 is the local time, the time is used as the local time without correction, while the latest outgoing / incoming call history from the mobile terminal 14 is used. When the time in the information is Coordinated Universal Time UTC, the time can be corrected to the local time.
　従って、本実施例のシステムによれば、車載情報処理装置１０が、ブルートゥース接続する携帯端末１４が車載情報処理装置１０に対して送信する発着信履歴情報がローカル時刻によるものであるか又は協定世界時ＵＴＣによるものであるかを事前に認識していなくても、携帯端末１４から取得した発着信履歴情報を車両乗員に提供するうえで、その時刻を常にローカル時刻とすることができる。このため、本実施例によれば、携帯端末１４での通話の発着信履歴情報を車載情報処理装置１０が扱って車両乗員に提供するうえでの時刻情報の正確性を向上させることができる。 Therefore, according to the system of the present embodiment, the in-coming / outgoing history information transmitted from the in-vehicle information processing apparatus 10 to the in-vehicle information processing apparatus 10 by the mobile terminal 14 connected via Bluetooth is based on the local time or the agreed world. Even if it is not recognized beforehand whether the time is due to UTC, the time can be always set to the local time in providing the vehicle occupant with the call history information acquired from the portable terminal 14. For this reason, according to the present embodiment, it is possible to improve the accuracy of the time information when the in-vehicle information processing apparatus 10 handles the call origination / incoming history information on the portable terminal 14 and provides it to the vehicle occupant.
　また、本実施例のシステムにおいては、車載情報処理装置１０とブルートゥース接続する携帯端末１４が変更されるときにも、その変更ごとにその携帯端末１４に対応して、車載情報処理装置１０がその携帯端末１４から取得した発着信履歴情報を車両乗員に提供するうえで適切な時刻補正を実施することが可能である。このため、本実施例によれば、車載情報処理装置１０とブルートゥース接続する携帯端末１４ごとに、その携帯端末１４での通話の発着信履歴情報の時刻情報を精度よく車載情報処理装置１０が扱って車両乗員に提供することができる。 Further, in the system of the present embodiment, even when the mobile terminal 14 connected to the in-vehicle information processing apparatus 10 via Bluetooth is changed, the in-vehicle information processing apparatus 10 corresponds to the mobile terminal 14 for each change. Appropriate time correction can be performed in providing the vehicle occupant with the call history information acquired from the portable terminal 14. Therefore, according to the present embodiment, for each portable terminal 14 that is Bluetooth-connected to the in-vehicle information processing apparatus 10, the in-vehicle information processing apparatus 10 handles the time information of the call origination / incoming history information on the portable terminal 14 with high accuracy. Can be provided to vehicle occupants.
　尚、上記の実施例においては、車載情報処理装置１０が情報取得するＧＰＳ衛星５５からのＧＰＳ信号に含まれる協定世界時ＵＴＣが特許請求の範囲に記載した「基準時刻」に、車載情報処理装置１０とブルートゥース接続されている携帯端末１４での通話終了後に該携帯端末１４から車載情報処理装置１０へ転送されるＰＢＡＰ情報に含まれる発着信履歴情報における時刻（特に、最終通話履歴の時刻）が特許請求の範囲に記載した「第１の時刻」に、車載情報処理装置１０がＧＰＳ衛星５５からのＧＰＳ信号に含まれる協定世界時ＵＴＣを用いて算出する、ブルートゥース接続されている携帯端末１４での通話時点の自車両位置におけるローカル時刻が特許請求の範囲に記載した「第２の時刻」に、ＢＴ２８，５４が特許請求の範囲に記載した「通信手段」に、それぞれ相当している。 In the above-described embodiment, the in-vehicle information processing apparatus is set at the “reference time” described in the claims by Coordinated Universal Time UTC included in the GPS signal from the GPS satellite 55 from which the in-vehicle information processing apparatus 10 acquires information. 10 is the time (particularly the time of the last call history) in the outgoing / incoming history information included in the PBAP information transferred from the mobile terminal 14 to the in-vehicle information processing apparatus 10 after the call on the mobile terminal 14 connected via Bluetooth is completed. At the “first time” described in the claims, the in-vehicle information processing apparatus 10 calculates using the Coordinated Universal Time UTC included in the GPS signal from the GPS satellite 55, and the Bluetooth connected mobile terminal 14 The local time at the position of the vehicle at the time of the telephone call is the “second time” described in the claims, and BT28 and 54 are in the claims. The mounting and the "communication means", corresponds respectively.
　また、車載情報処理装置１０の制御回路４２が、ブルートゥース接続する携帯端末１４に対する発着信履歴情報を含むＰＢＡＰ情報の転送要求に従って該携帯端末１４が送信するＰＢＡＰ情報を受信して取得することにより特許請求の範囲に記載した「第１の情報取得手段」が、ＧＰＳ衛星５５からのＧＰＳ信号に含まれる協定世界時ＵＴＣを取得することにより特許請求の範囲に記載した「第２の情報取得手段」が、ブルートゥース接続されている携帯端末１４での通話終了後に該携帯端末１４から転送されるＰＢＡＰ情報に含まれる発着信履歴情報における時刻と、車載情報処理装置１０がＧＰＳ衛星５５からのＧＰＳ信号に含まれる協定世界時ＵＴＣを用いて算出する、ブルートゥース接続されている携帯端末１４での通話時点の自車両位置におけるローカル時刻と、の差を算出することにより特許請求の範囲に記載した「算出手段」が、その算出した差が所定以上である場合に、携帯端末１４から転送されるＰＢＡＰ情報に含まれる発着信履歴情報における時刻を車両側で扱ううえでローカル時刻と協定世界時ＵＴＣとの時差分だけ補正を行うことにより特許請求の範囲に記載した「補正手段」が、それぞれ実現されている。 Further, the control circuit 42 of the in-vehicle information processing apparatus 10 receives and acquires the PBAP information transmitted by the mobile terminal 14 in accordance with the transfer request of the PBAP information including the outgoing / incoming history information for the mobile terminal 14 connected via Bluetooth. The “first information acquisition unit” described in the claims acquires the Coordinated Universal Time UTC included in the GPS signal from the GPS satellite 55 to obtain the “second information acquisition unit” described in the claims. Is the time in the outgoing / incoming call history information included in the PBAP information transferred from the mobile terminal 14 after the end of the call on the mobile terminal 14 connected via Bluetooth, and the in-vehicle information processing device 10 converts the GPS signal from the GPS satellite 55 into Calculated using the Coordinated Universal Time UTC included in the mobile terminal 14 connected via Bluetooth. The "calculation means" described in the claims by calculating the difference between the local time at both positions is included in the PBAP information transferred from the portable terminal 14 when the calculated difference is greater than or equal to a predetermined value. In order to handle the time in the outgoing / incoming call history information on the vehicle side, the “correction means” described in the claims is realized by correcting only the time difference between the local time and the Coordinated Universal Time UTC.
　ところで、上記の実施例においては、携帯端末１４での通話の発着信履歴情報を車載情報処理装置１０が扱ううえで時刻の補正を行うものであるが、本発明はこれに限定されるものではなく、携帯端末１４でのメールの発着信履歴情報を車載情報処理装置１０が扱ううえで時刻の補正を行うものであってもよい。 By the way, in the above embodiment, the time correction is performed when the in-vehicle information processing apparatus 10 handles the call origination / incoming history information on the mobile terminal 14, but the present invention is not limited to this. Alternatively, the time correction may be performed when the in-vehicle information processing apparatus 10 handles the outgoing / incoming history information of the mail at the portable terminal 14.
　また、上記の実施例においては、車載情報処理装置１０の制御回路４２が、ブルートゥース接続されている携帯端末１４での通話終了後に該携帯端末１４から転送されるＰＢＡＰ情報に含まれる発着信履歴情報における時刻と、車載情報処理装置１０がＧＰＳ衛星５５からのＧＰＳ信号に含まれる協定世界時ＵＴＣを用いて算出する、ブルートゥース接続されている携帯端末１４での通話時点の自車両位置におけるローカル時刻と、の差を算出して、その差が所定以上である場合に、携帯端末１４から転送されるＰＢＡＰ情報に含まれる発着信履歴情報における時刻を車両側で扱ううえでローカル時刻と協定世界時ＵＴＣとの時差分だけ補正を行うこととしている。しかし、本発明はこれに限定されるものではなく、制御回路４２が、ブルートゥース接続されている携帯端末１４での通話終了後に該携帯端末１４から転送されるＰＢＡＰ情報に含まれる発着信履歴情報における時刻と、車載情報処理装置１０がＧＰＳ衛星５５からのＧＰＳ信号ブルートゥース接続されている携帯端末１４での通話時点の協定世界時ＵＴＣと、の差を算出して、その差が所定以上である場合に、携帯端末１４から転送されるＰＢＡＰ情報に含まれる発着信履歴情報における時刻を車両側で扱ううえでローカル時刻と協定世界時ＵＴＣとの時差分だけ補正を行うこととしてもよい。 In the above embodiment, the control circuit 42 of the in-vehicle information processing apparatus 10 makes outgoing / incoming history information included in the PBAP information transferred from the mobile terminal 14 after the call on the mobile terminal 14 connected via Bluetooth ends. And the local time at the position of the vehicle at the time of the call on the Bluetooth-connected mobile terminal 14 calculated by the in-vehicle information processing device 10 using the Coordinated Universal Time UTC included in the GPS signal from the GPS satellite 55 If the difference is greater than or equal to a predetermined value, the local time and the coordinated universal time UTC are used to handle the time in the outgoing / incoming call history information included in the PBAP information transferred from the mobile terminal 14 on the vehicle side. The correction is made only for the time difference. However, the present invention is not limited to this, and the control circuit 42 uses the transmission / reception history information included in the PBAP information transferred from the mobile terminal 14 after the call on the mobile terminal 14 connected via Bluetooth is terminated. When the difference between the time and the Coordinated Universal Time UTC at the time of a call on the mobile terminal 14 to which the in-vehicle information processing apparatus 10 is connected via the GPS signal Bluetooth from the GPS satellite 55 is calculated and the difference is greater than or equal to a predetermined value In addition, when handling the time in the outgoing / incoming call history information included in the PBAP information transferred from the mobile terminal 14 on the vehicle side, the time difference between the local time and the Coordinated Universal Time UTC may be corrected.
　また、上記の実施例においては、車載情報処理装置１０が情報取得するＧＰＳ衛星５５からのＧＰＳ信号に含まれる協定世界時ＵＴＣを、携帯端末１４から取得するＰＢＡＰ情報に含まれる発着信履歴情報における時刻の補正を実施するか否かを判定するうえで必要な「基準時刻」とすることとしているが、本発明はこれに限定されるものではなく、車載情報処理装置１０が情報提供を受ける外部の情報センタなどが送信してその車載情報処理装置１０が情報取得する時刻情報をその「基準時刻」とすることとしてもよい。 In the above-described embodiment, the Coordinated Universal Time UTC included in the GPS signal from the GPS satellite 55 acquired by the in-vehicle information processing apparatus 10 is included in the outgoing / incoming call history information included in the PBAP information acquired from the mobile terminal 14. The “reference time” necessary for determining whether or not to correct the time is used, but the present invention is not limited to this, and the in-vehicle information processing apparatus 10 receives information from the outside. The time information transmitted by the information center or the like and acquired by the in-vehicle information processing apparatus 10 may be set as the “reference time”.
　更に、上記の実施例においては、車載情報処理装置１０と携帯端末１４とが、互いに近距離無線通信を行うブルートゥース接続される情報提供システム１２が用いられているが、本発明はこれに限定されるものではなく、車載情報処理装置１０と携帯端末１４とが有線接続される情報提供システムに適用することとしてもよい。 Furthermore, in the above-described embodiment, the information providing system 12 in which the in-vehicle information processing apparatus 10 and the mobile terminal 14 are connected via Bluetooth for short-range wireless communication is used.
